1. first U have to find and customize a new theme. This one os too cold. Fot that I'll rather see agresive colors like red or yellow (or both of them - or U can use a very clear blue color).
2. Logo - yes I agree with Jensclas! Tis one, U use on your page is ... hmmm what can I say? If U want something similliar to a logo like on that
page just give me a word! I'll do it 4 U free.
3. modules? yes - once again I agree with Jensclas - news module U use is owfull! (or is it just a block?).
As U see first find and customise your theme. remember about left and right column "width" defined in the style.css file! (don't use pictures with width wider than those proportions)
